Changes in version 2.1: * A few more portability bugs have been fixed. The version number has been changed from 2.0.12g11 to 2.1, because the name `patch-2.0.12g10' was too long for traditional Unix file systems. Versions 2.0.12g9 through 2.0.12g11 fix various portability bugs. Changes in version 2.0.12g8: * Start of the 12g series, with a GNU-style configure script and long-named options. * Added the -t --batch option, similar to -f. * Improved detection of files that are locked under RCS or SCCS. * Reinstate the -E option to remove output files that are empty after being patched. * Print the system error message when system calls fail. * Fixed various bugs and portability problems.
